Melamine tableware is made of melamine, and the units of melamine are formaldehyde and melamine. These two units have the characteristics of non-toxic, tasteless, odorless, high hardness, high temperature resistance, moisture resistance, good stability and crack resistance. The plastic surface is smooth and shiny, and no harmful substances are produced when synthesized at 54-80 degrees Celsius. .
Let's take a look at the technical indicators of melamine tableware. Because the difference between the theoretical curing degree and the actual curing degree of melamine products will be affected by acid, alkali, alcohol, etc. The manufacture of melamine plastic products has the following requirements:
1. Impact resistance, bending resistance, heat resistance, etc. The hygienic standard indicators of surface amine plastic products should meet the requirements of GB9690-88 and QB1999-84.
2. The amount of formaldehyde that can be extracted should be less than or equal to 1.0 mg/L.
3. When making surface amine tableware, the consumption of potassium permanganate should be less than or equal to 3 mg/L.
The main component of imitation porcelain tableware is melamine resin, which is synthesized from formaldehyde and melamine. If the two do not polymerize well, melamine will remain in the tableware. When buying imitation porcelain tableware, be sure to read the tableware description to prevent buying fake tableware.
In short, melamine tableware is non-toxic and tasteless, resistant to bumps, corrosion, high temperature and low temperature. Compact structure, strong hardness, not easy to break, strong durability. When we buy, we must first buy in regular stores and supermarkets, and don't be greedy and buy at street stalls. Secondly, when we buy, we should check whether the utensils have obvious deformation, color difference, smooth surface, uneven bottom, clear decal pattern, whether there are wrinkles or air bubbles. Prevent quality problems from affecting use.
